Autocar drives the Audi A1 with Wankel range-extender

Wrote: What is it?

The A1 e-tron is a version of the new A1 hatchback and can probably be the title of the first true extender’ electric car.

It is primarily by an electric motor the front wheels, powered by a battery pack. However, the battery is exhausted, a tiny engine (mounted under the floor) kicks in and drives a which, in turn, powers the motor. Like nearly all cars, the A1 has a single speed

The combination of a (three-hour) full charge from the household and the petrol in the car’s three-gallon gives a claimed 148mpg on the upcoming EU electric vehicle cycle.

The motor is good for 60bhp and ft of torque on a continuous basis, but is of 101bhp and 177lb ft for short

In place of the usual ICE transmission, the A1 nose not only gets the motor, but also houses a inverter, the motor’s electronic system, a battery charger, a 12v battery and a high voltage air compressor.

Situated in the rear of the transmission tunnel and under the seats is the car’s Sanyo battery pack. A relatively 12kWh (half the size of pack used by the Nissan will take the A1 around 31 in most normal conditions, enough range for the average or US commute.

What makes the A1 really special is the ‘Range generator module’. This is around a tiny, 245cc, rotar, Wankel engine. It a maximum 20bhp, driving a which provides electricity the battery has been run down to its charge.

The Wankel engine, generator, electronics, induction and exhaust have been combined a module that weighs 65kg and fits under the boot floor, without luggage space. There’s room under the floor for the Hi-Fi’s bass booster.

The Volt was trailed by GM as being a extender but, in certain situations, the Volt’s engine can be directly to the car’s electric The A1 e-tron, however, is a true extender in that the engine is not in any way to the wheels.

This completely new has not changed the A1 in any significant way. The external differences are the Carbon Reinforced Plastic roof and wheels. Compared to the massively Mini E, the A1 e-tron is in another

What’s it like?

Genuinely Even though our test was on a circuit, it’s hard to that the e-tron is not showroom In fact, much of development was in virtual reality and real-world with members of the public in Paris this summer.

In electric mode it is swift and and handles very tidily. the extra weight of the range running gear, the A1 had enough to be interesting.

Under hard it is satisfyingly quick and impressively After a few laps of the circuit was laid out to imitate town and a few full-bore accelerative runs, I to the engineer in the passenger seat ‘I hadn’t got the Wankel to kick in’.

In fact, it four times. It was so quiet, so insulated and so inherently smooth I just hadn’t noticed. claims that further improvements are in the pipeline.

Using the stock automatic lever, the driver can select ‘D’, ‘R’, ‘N’ or the latter allowing the engine to cut in an out normal driving to help the battery.

Not all Range Extender will be this well or refined, but this system has to be the way for production electric vehicles. Not does it completely overcome anxiety’ but it’s also more cost-effective than a range, pure EV.


For example, the saved by using a battery the size of the one in the Nissan Leaf, is far than than cost of the A1’s range extender

Should I buy one?

If you could, I’d it very highly. But you can’t. And the A1 e-tron’s advanced state, it is some way from being the green light by Audi’s

Insiders hint that the strategy is to first introduce motivation on high-end Audi That would be a huge This A1 is far more sophisticated and ready than the R8 e-tron, is scheduled for small-scale production in

On this limited showing, say it was also better than Volt.

Of anything Audi has in the last decade, it is probably exceptional car which best up to the company’s ‘Vorsprung Durch mission statement. It really has to its way into the showroom.
